the area of the equilateral triangle will be equal to root 3 by 4 into 144 that equals to 36 root 3 by 5 and when we divide 36 root 3 by 5 / 5 we get an answer
JOELWILSON2004:
how does the equilateral triangle be equal to 3 by4 into 144
bcoz it is,, root 3 by 4 into side square
ok into144 why
bcoz side is 12 so square of 12 is 144 I guess
do u know hw to do this in herons formula
I ve just checked from herons formula also area is 36 root 3
once see my answer
pls be detailed
like below
sorry

Area of an equilateral triangle is √3/4 x S^2
= √3/4 x (12)^2
= √3/4 x 144 (144 cancels with 4, 36 times)
= √3 x 36
= 36√3 m^2
Cost of levelling = (5 x 36√3)rupees
= 180√3 rupees
